Message Reconciliation During Disaster Recovery |
| 摘要 |
A mechanism is provided for message reconciliation during disaster recovery in an asynchronous replication system. A message is intercepted at a gateway remote from a primary data centre to which the message is being sent. A copy of the message request is stored in a request message history remotely from the primary data centre. The message is forwarded to the primary data centre. A transaction history of the message request is stored at the primary data centre which is mirrored to a disaster recovery site with other data from the primary data centre. In response to determining that the primary data centre has failed, messages in the request message history are compared with messages in the transaction history as retrieved from the disaster recovery site. |

1. A method, in a data processing system, for message reconciliation during disaster recovery in an asynchronous replication system, the method comprising:
intercepting a message at a gateway remote from a primary data centre to which the message is being sent; storing a copy of the message in a request message history remotely from the primary data centre; forwarding the message to the primary data centre; storing a transaction history of the message at the primary data centre which is mirrored to a disaster recovery site with other data from the primary data centre; and in response to determining that the primary data centre has failed, comparing messages in the request message history with messages in the transaction history as retrieved from the disaster recovery site. |
